This-invention relates to" a rail oint of the type that :includes a base plate extending beneath and supporting the base of adjacent rail ends and in which a joint plate is rigidly secured tosaidbase plate such as is shown in my prior Patents; #1',399,572 ofDecember 6, 1921, #1,442,29l'0f January 16,1923, and #1,517,124 of November 25, 1924, upon which this invention is an improvement. A principal object of this invention is to provide a rail joint including means to'cau'se that side of the head of the rail that faces, the flange of the wheel to be slightly inclined a inwardly away from said flange so that the '1iabi1ity of the flange engaging a rail head that is slightly out of alignment is reducedto a minimum.

A furtherobject of this invention is to.

} provide a rail joint, including a baserplate' that normally extendsb'eneath andsupports the rail ends, and a joint platesecured in lapped relation to saidfbase plate, in which the removal and insertion of thesecuring V means that passes through the lappedportions of said plates' is' facilitated. .A stillfurther object of this invention is to provide a rail joint including a base plate, arranged beneath-the ends of adjacent rails, that is provided with means tocause said plate to penetratethe surfaceof the under lying ties when. secured thereto, in such man ner that creeping of the base plate relative to the ties isprevented Still further objects of this invention-will appear as a description thereof proceeds w'ith reference to the accompanying drawings in which: V Figure 1 is a sectional View through a rail adjacent the improved. joint of this invention. Figure 2 is' a perspective view. of the base plate.

I} M Figure 3 is a. perspective view of'the joint plate thatis attached to the'base plate.

Figure .4 is aside view of lthe base plate shown in Figure 2, viewed from the left side I of said figure. I 7

Like reference 7 characters indicate like parts throughout the-several views. I f The numeral 5 indicates a base. plate formed to rest upon adjacent ties and to receive the adjacent ends of a pair of rails. One of these 'rails'is designated by the nug meral 6 on Figure 1. Base plate .5. isp'ro vided adjacent one side thereof with a flange 7 overhanging aportion of a supporting surface 8Eof the base plate. Said .flange is spaced above said supporting surface. and provides a recess 9 to snugly receive a portion 10. of the base of each of the adjacent rails. r s

The supporting surface 8 of the baseplate. 5 is slightly inclined toward therecess '9 as indicated on Figure 1. This inclination is formed'by providing the base plate 5 that is of gradually increasing thickness from the 5 side thereof that carries the flange 7 toward 7 the other side of the base plate. It will be apparent that by this arrangement the rails 6 are supported so that they are slightly in clined with respect to the vertical. Accord O ingly, the side 11 of the head 12 Oflfl-ll 6 that engages the flange ofthe car wheels, one of which is shown at13 in Figure 1, is slightly inclined away from the flange 14 of said Base plate 5 is provided'in its undersurface with a series of grooves15 (Fig. 4) positioned and formed to bite intothe ties arranged therebeneath, when the base plate is attached to the ties whereby creeping of the base plate with respect to the tie is prevented. Ifpdesi'red, these grooves may be .made in any'other manner that willprovide projections that can be; forced into theties that underlie the base plate. p 1 The side; of he base plate 5 opposite the flange 7 is offset upwardly as shown at 16 s and is provided with a plurality of elongated slots 17- disposed at suitable intervalsalong 90 said offset portion. V r

The adjacent ends oftherails that are arranged uponthe base plate 5Jare rigidly SQ.

cured together by a pairof joint plates 18 and 19 disposed on opposite sides of the rails between the head and base thereof as clearly shown inFigure 1. Said plates are rigidly clamped together with the web of the rail between then'i, by bolts 20 extendingthrcugh oval openings 21 and 22 inQthe plates 18 and 19 respectively, and through an enlarged opening 23 in the web of the rail. The plates 18 and 19 and the rail are rigidly clamped together by a nut 24 threaded on the end of bolt 20 and a lock nut 25.

Joint plate 18 is provided with a tongue 26 and an offset side 27 arranged to lie over the offset portion 16 of the base plate 5. The offset portion of the'joint plate 18 is provided with a plurality of spaced elongated openings 28 arranged to register approximately with the openings 17 in the ass plate 5. It will be observed by a comparison of Figs. 2 and 3 that the major axes of the elongated openings 17 in base plate 5 and of the elon-' gated openings 28, just described, extend at right angles to each other. This arrangement permits the openings to be readily brought into registry to receive bolts 29, the heads 30 of which are arranged in the space provided by the offset 16 in the base plate 5. The bolt 29 is provided with a non-circular shank adjacent the head thereof, saidinon circular shank being arranged to enter the elongated openings 17 in the base plate 5, so that the rotation of the bolt will be prevented when the nuts 30 and 31 are adjusted to rigidly clamp the base plate 5 and the joint plate 18 together with a portion of the base of adjacent rails between them.

By supporting the rail in a slightly inclined position so that the face 11 of the head thereof recedes away from the flange 14, the likelihood of rupturing the rail joint by the wheel flanges, if the adjacent rails are slightlyout of alignment is greatly reduced, since the face 11 of the improperly aligned rail is largely out of the path of the flange 14, so that the shock applied'to the improperly aligned rail by the flanges of the Wheels is reduced to a minimum. By offsetting the ends of the base and joint plates. as above described,,the entry of the securing bolts 30 is greatly facilitated and by providing the base plate with grooves 15, forming, in effect, teeth that bite'into the surface of the ties, creeping of the base plates relative to the ties is substantially prevented.

The invention maybe embodied in other specific forms without departing from the spirit or essential characteristics thereof; The present embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather.

' than by the foregoing description and all changes which come within the meaning and I range of equivalency of the claims are thercfore intended to be embraced therein.
